Answer:
3x+4
Step-by-step explanation:
When simplifying expressions, you need to combine like terms. 5x and -2x combined would equal 3x. Since the 2x was negative, you needed to subtract. Next, you combine 3 and 1, which should equal 4.
When putting the expression back together, make sure you leave it in the same order as received. This would mean you would put the coefficient with the variable first, and then put the whole number.
Make sure to take the signs into account. If it is negative, you subtract, and if it is positive, you add.
Hope I helped!
W varies directly as r cubed and inversely as s. If w=24 when r= 4 and s= 8, find out when w= 81 and s= 27?
Translating the word problem into a symbolic statement: W = kr³/s. Find k by letting W = 24, r = 4 and s = 8:
k·4³
24 = --------
8
This reduces to 3 = 4^3*k, or 3 = 64k, or k = 3/64 (the constant of proportionality).
3r^3
w = ---------

Sean runs 2/3 of a mile in 10 minutes. at this rate, how many miles can Sean run in 30 minutes? Explain how you found this answer. Please I need it quick!
Answer:
2 miles.
Step-by-step explanation:
In this case, we would multiply the numerator by 3 since we know that it takes him 10 minutes to run 2/3 of a mile. So, 2x3 = 6. Which gives us 6/3. Simplified that would be 2 miles. Hope this helps!

120 coins what is the ratio if 2/6 is nickels and 2/6 are dimes and the rest is quarters. What is the ratio of nickels to dimes to quarters?
Hi there!
If the nickels and dimes ratioe are both 2:6, then the quarter is also 2:6.
The total of of all together is also 6:6 and 6:6 is also 120 coins.
120 divide by 3 different kinds of coins are 40.
This means that there are 40 of 1 coin out of 3 different kinds of coins. What I really mean is that each coins all have 40 each...
Therefore, the ratios of nickels to dimes and to quarters are 40:40:40...

For her phone service, Maria pays a monthly fee of $19, and she pays an additional $0.05 per minute of use. The least she has been charged in a month is $72.35. What are the possible numbers of minutes she has used her phone in a month? Use m for the number of minutes, and solve your inequality for "m".
Answer:
m=1067
Step-by-step explanation:
19 +.05m = 72.35
72.35-19 = 53.35
53.35/.05= 1067
m=1067

Find the value of x in this proportion.
621=10x
Answer:
x = 62.1
Step-by-step explanation:
Note the equal sign in this equation, what you do to one side, you do to the other. Isolate the variable, x, by dividing 10 from both sides of the equation:
[tex]621 = 10x\\\\\frac{621}{10} = \frac{10x}{10} \\\\x = \frac{621}{10} \\x = 62.1[/tex]

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of campers who voted for hot dogs = 5 campers
Let the number of campers who voted for sphagetti = 4 campers
Now , the total campers = 5 + 4
= 9 campers
5 out of 9 campers vote for hot dogs
So ,
The total number of campers = 72 campers
The equation will be ,
The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72
The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72
= 5 x 8
The total number of campers who voted for hotdogs = 40 campers
Hence , The number of campers who voted for hotdogs is 40 campers

Suppose you are planning on picking up a friend or family member at the airport. You want to park and walk in to meet them in the terminal. The Orlando International Airport has two options listed on their website:
Option 1: Park at either the North or South Park Place Economy Lot
Grace period (free) for the first 10 minutes
$5 for 11 minutes to 3 hours, then
$10 per 24-hour period
Free shuttle to the terminal
Option 2: Park at any of the parking garages
Grace period (free) for the first 20 minutes
$2 for 21 to 30 minutes, then
$1 for each additional 15 minutes (or any part thereof from the time of entry) up to a maximum of $17, then $17 per 24-hour period
How should someone make a decision about where to park to pick up their friend/family member? When is each option the most cost-effective?
Answer:
A) To make a decision on where to park depends on
Time to spent on parking cost of parking within the time to be spent on parkingIncentivesB) Option 1 is most cost effective when the parking time is ≥ 3hours
while Option 2 is most cost effective when the parking time is ≤ 30 minute
Step-by-step explanation:
A) To make a decision on where to park depends on
Time to spent on parking cost of parking within the time to be spent on parkingIncentivesB)
lets assume you will be parked for 30 minutes before picking up your friend
For option 1
You will spend $5 and also get a free shuttle to the terminal
For option 2
You will spend $2
Therefore Option 2 is better
Lets assume you will be parked for 3 hours before pick up
For option 1
You will spend $5 and also get a free shuttle
For option 2
You will spend ; $2 for the first 30 minutes + $10 for the remaining 2hours 30 minutes
Therefore Option 1 is better.
Option 1 is most cost effective when the parking time is ≥ 3hours
while Option 2 is most cost effective when the parking time is ≤ 30 minutes
Need help ASAP
questions in the pics i have sent
Answer:
Step-by-step explanation:
Picture 1
In right triangle ABC,
Side AB is the opposite side of angle C.
Picture 2
In triangle MKL,
tan(∠M) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{KL}{KM}[/tex]
= [tex]\frac{15}{8}[/tex]
Option (1) is the answer.
Picture 3
In ΔXYZ,
sin(∠Z) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{XY}{XZ}[/tex]
For the length of XY we will apply Pythagoras theorem in ΔXYZ,
XZ² = XY² + YZ²
XY² = XZ² - YZ²
= (40)² - (32)²
XY = √576
= 24
sin(Z) = [tex]\frac{24}{40}[/tex]
sin(Z) = [tex]\frac{3}{5}[/tex]
Picture 4
In right triangle DEF,
Cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{EF}{DF}[/tex]
= [tex]\frac{75}{72}[/tex]
= [tex]\frac{25}{24}[/tex]
Picture 5
In ΔABC,
tan(63°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(63°) = [tex]\frac{BC}{AB}[/tex]
AB = [tex]\frac{BC}{\text{tan}(63)}[/tex]
AB = [tex]\frac{8}{\text{tan}(63)}[/tex]
AB = 4.0762 ≈ 4 m
Option (3) will be the answer.

Answer:
2 9/14
Step-by-step explanation:
first we must make 1/6 and 3/7 have common demoniaters! (or however u spell it)
1/6 x 7/7 = 7/42
3/7 x 6/6 = 18/42
7/42 + 18/42 = 25/42
2/7 x 6/6 = 12/42
25/42 + 12/42 = 37/42
37/42 + 7/42 = 44/42
44/42 + 18/42 = 62/42
62/42 + 12/42 = 74/42
5/7 x 6/6 = 30/42
74/42 + 30/42 = 104/42
104/42+7/42 = 111/42
111/42 = 2 9/14
List three factors that must be considered when designing and building a house? Describe how each factor can influence the design and the building of the house.
I will be giving brainiest to correct and best explained answer! :)
Step-by-step explanation:
I would say the area its getting built. imagine wanting to build a house but you can't dig the sewer (if thats the spelling) pipes bc the area you want doesn't have any water or something like that. definitely money. without it, you can't do anything, you can't buy materials or even hire people to help you because you cannot tell me that you can build a house on your own. Another I would say is Labor cause like I said, if you ain't got nobody to help you, you're probably going to take a few years or more. so if you want to build a house in an area where there is a few architects and designers, you're just going to have to suck it up and get what you get.

2. Find the median of the upper quartile (70 - 80.)
3. Find the median of the lower quartile. (60 - 70.)
4. Subtract the lower quartile from upper quartile.
1. median of the data = 70
2. median of Q2 = 75
3. median of the Q3 = 65
4. 75 - 65 = 10
